Application of Salicylic Acid Derivative in Modifying the Iron Nutritional Value of Lettuce ( L.).

The present experiment addressed the effects of foliar sprays of different iron (Fe) concentrations (mg L), i.e., 2.

Microgreens Biometric and Fluorescence Response to Iron (Fe) Biofortification.

Microgreens are foods with high nutritional value, which can be further enhanced with biofortification. Crop biofortification involves increasing the accumulation of target nutrients in edible plant tissues through fertilization or other factors. The purpose of the present study was to evaluate the potential for biofortification of some vegetable microgreens through iron (Fe) enrichment.

Naturally based ionic liquids with indole-3-acetate anions and cations derived from cinchona alkaloids.

The use of highly efficient methods and natural raw materials in syntheses of new biologically active substances addresses the current challenges in this area: ensuring the highest possible efficacy at low concentrations and reducing negative environmental impact. In the present study, we applied this strategy to obtain a new group of ionic liquids containing the indole-3-acetate anion, which is a well-known plant growth hormone, and a cation derived from a cinchona alkaloid - quinine or quinidine. A comparison of the derivatization kinetics of both alkaloids was also carried out, and the use of a quaternary quinidine derivative as a source of biologically active ionic liquids is described here for the first time.

The Content of Phenolic Compounds and Organic Acids in Two Cultivars Flowers and Its Dependence on Light Colour and Substrate.

The main focus of the study was to determine the content of phenolic acids, flavonoids, and organic acids in the flowers of 'Petite Gold' and 'Petite Orange'. The growth of the plants was assessed depending on the cultivation conditions. The above plants were illuminated with white light, whereas the 'Petite Gold' ones with white light enhanced with blue or red light.

How does the content of nutrients in soil affect the health status of trees in city parks?

Trees have multi-aspect influence on the microclimate in urbanised areas. Therefore, it is important to investigate the biotic and abiotic factors affecting their health. The aim of the conducted study was to assess the chemical composition of soils and the nutritional status of lime and horse chestnut trees in selected sites and the influence of these factors on the condition and health of these tree species in urbanised areas.

Effect of increasing manganese concentration in nutrient solution on the antioxidant activity, vitamin C, lycopene and polyphenol contents of tomato fruit.

This study evaluated the effect of increasing manganese (Mn) nutrition on the content of antioxidative compounds such as vitamin C, lycopene and polyphenols, and the antioxidant activity of tomato (Lycopersicon esculentum Mill., cvs 'Alboney F1' and 'Emotion F') fruit. Plants were grown in rockwool using a nutrient solution with the following content of Mn (mg dm): 0.

Effect of residual monomer from polyacrylamide on head lettuce grown in peat substrate.

The paper investigates the migration of the acrylamide monomer (AMD) to lettuce chosen as a test plant growing in an organic medium (peat substrate). Polyacrylamide (PAM)-based flocculant added to the growing medium contained no more than 1000 mg kg(-1) of AMD. Plants were grown with varied doses of PAM preparation (0.

The effect of choline-stabilized orthosilicic acid on microelements and silicon concentration, photosynthesis activity and yield of tomato grown under Mn stress.

The aim of experiments was to assess the efficiency of choline-stabilized orthosilicic acid (ch-OSA; complex of orthosilicic acid with choline and a bioavailable source of silicon) application under increasing manganese (Mn) stress on the micronutritional composition and yielding of tomato (Solanum lycopersicum L. cvs. 'Alboney F1' and 'Emotion F1').
